What is Rigid Flex?
Rigid flex printed circuit boards provide designers with one of the more unique packaging methods for electronic designs.

Combining the component and routing density of hardboards with the flexibility of flexible circuits, rigid flex PCBs allow designers to achieve routing density and interconnectivity that is not available in other types of circuit boards.

Primarily used in military, medical and camera applications, rigid flex PCBs comprise about 1% of the overall PCB market, but they are increasingly used in other electronic applications.

They cost more than traditional hard boards and flexible circuits due to the raw materials required; but, in the right applications, rigid flex PCBs dramatically outperform traditional rigid and flexible circuit boards, and they can be more cost-effective in a full solution.

When Should You Use Rigid Flex?

1. When a designer needs a flexible solution and needs to rout components on both sides of the PCB

2. When a designer requires electronics fit the device, rather than the device conform to the electronics

3. When the electronic components and connectivity required max out space for connectors and flex cables

4. As a single-package solution for electronics with high input/output connectivity

5. As a cost-effective alternative to a combined assembly of interconnected hard boards

6. When the designer has to miniaturize their design to accommodate greater functionality

7. In weight-saving applications, such as drones, unmanned vehicles, aerospace and space applications

8. In high vibration environments

9. In high shock applications, where electronics will be subjected to 10,000 G’s or more

10. In never-fail electronics

Features

Q: What is the smallest PCB size I can have?

A: Printed circuit boards are used in a variety of electronic products and therefore can be manufactured in a number of sizes.

Board sizes vary, dependent on customer requirements with the smallest pcb size that we have made being only 5mm square, for a miniature medical device.

Your PCBs can be made in a size to suit your requirements, however, there are a number of factors to consider, including product size, single sided, double sided plated through hole or multilayer, as well as number and weight of components, and the board’s finished application.

Each panel of boards will require a border for tooling holes, traces and coupons, and space for routing. Large panels with many circuits often have a poor manufacturing strength and therefore need to be reinforced, whilst smaller circuit boards may be stronger.

Small and irregular shaped PCB’s can also be made using our precision CNC routing machine and left in a routed panel with pips, or rectangular boards can be scored with pips.
